A. l.. HENRY ET AL TROLLEY Filed August 5, 1925 BAGKWARD 4 wuenfow l/ndrew [..Henrq Giles SMoore provided at opposite sides of the trolley to limit the movement of the same in the contrary direction, the location of the stops 23 being at the opposite extreme position of the harp from the position where the lugs 21 contact with it.

The trolley has a dat faced Central bearing portion at Ql through which the pin 12 passes, and copper plates 25 are riveted to said pin by copper rivets 26, said plates bearing against the forks 11 of the harp with their outer faces. This construction insures permanent electrical Contact of the trolley and the harp, and thus provides for an uninterrupted low of current. 'Ilo save material and to make the trolley as light as possible, the frame of the trolley is skeletonized so far as possible, as by providing narrow ribs 27, 28 and 29 While leaving the intervening space open. These ribs connect the trolley bearing 24 respectively to the side piece 20', the bridge 18 and the shoe 14 and each rib is at right angles to its side of the trolley, While ribs 27 and 29 are nearly alined when in normal position. In a preferred construction there are diverging ribs 29 merging into the flanges 13 and 14, lout this and other details are subject to variations in accordance with the purposes of our invention.

It will be obvious to those skilled in the art that various changes may be made in our device Without departing from the spirit of the invention and therefore We do not limit ourselves to what is shown in the drawings and described in the specification, but only as indicated in the appended claims.

Having thus fully described our said invention what we claim as new and desire to secure by Letters Patent is:

1. In a trolley, an approximately rectangular structure comprising a shoe bearing against the Wire during movement in one direction, a Wheel engaging the Wire during movement in the reverse direction, a bearing therefor, a bridge between the Wheel and the shoe also engaging the wire during such reverse movement, a harp, a pin carried by the harp, a bearing on the trolley for said pin, and slreletonized supporting means for such parts including relatively slender side members connecting the Wheel bearing with said shoe, and relatively slender cross ribs connecting the Wheel bearing respectively to the shoe the bridge and one or more of said slender side members, substantially as set forth.

2. A trolley as in claim 1 having lugs eX- tending` inward from said Wheel bearings, and lugs on the harp engaging the firstnamed lugs to limit oscillation of the trolley in one direction, substantially as set forth.

3. A trolley as in claim 1, the sides of the shoe overhang-ing the adjacent parts of the harp, lugs on the trolley normally Covered by said overhanging parts, and abutments on the harp for engagement by the iirst named lugs to limit oscillation of the trolley in one direction, substantially as set forth.

In Witness whereof, We have hereunto set our hands and seals at Indianapolis, Indiana, this 1st day of August, A. D. nineteen hundred and twenty-live.
